Simple explanation: when you scale all of the sides of a prism, the volume changes by the scale factor CUBED (it's distributing to all of the sides)

Just put in your calculator:

\frac{390}{18^3} - \frac{390}{24^3}

(We know that 18*18*18 is going to be larger than 24*24*24, and when you divide something by a larger number, it's going to be less, so the 1:24 model is going to have a lesser volume)
and you should get an answer about equal to

\boxed{0.04\ in^3}

(I'm pretty sure your teacher doesn't want a fraction, because the exact answer is \frac{2405}{62208})

Marysya12 [62]

Usando proporciones, se encuentra que 400 africanos han participado.

En total, hay x participantes.

\frac{5}{6} de los corredores son europeos, o sea:

E = \frac{5x}{6}

Los americanos son la dècime parte de los europeos, o sea:

Am = \frac{1}{10}E = \frac{5x}{60} = \frac{x}{12}

Los africanos son la quinta parte de los americanos, o sea:

Afr = \frac{1}{5}Am = \frac{x}{60}

En la carrera han inscritos 24 000 participantes, o sea, x = 24000. Por eso, la cantidad de africanos es:

Afr = \frac{x}{60} = \frac{24000}{60} = 400
